Bow ron' Application filed October as, 1927, Serial Myinvention relatesto bowsand relates particularly'to bows for archery of the typepermitting dissembling of the bow durlng periods of non-use into twoparts for convenience in transporting the bow.

It'has been proposed to construct bows,

intended for various archery purposes, of

steel, and moreover it has been recently proposed to construct a bowcomprising-a pair .of halves each similarly made'of solid steel, taperedtoward their tips and ribbed on their rear sides in such a way as toaccomplish the properties of distributed weight and resiliency desiredto be had in bows to a very marked degree.

Heretofore also it has been proposed to provide a bow for archery havinga pair of wooden limbs joined together in a handle so as to permit thelimbs to be removable from the handle, whereby the space occupied by thebow in transportation is approximately decreased by one-half.

However, in order to prevent the halves from being displaced relative tothe handle, it has previously been necessary, so far as I am aware, tosecure the handle and bow halves together by pins or the like, whichhave various objections such as being inefiicient in the main purpose ofjoining the handle to the bow halves, coming loose after a number ofoperations and the like.

An object, therefore, of my present invention is to provide meansparticularly adapt-' able for bows having halves of non-circular solidsectional form, a securing means whereby 'the' handle or paradoxsupporting the handle may be removably secured to one or both halves ofthe bow.

Another object of my invention is to provide for the removably securingof a bow halve to a handle paradox without the necessity of employingpins or liek interlocking means which are susceptible to Wear and tearto which the bows are subjected in practice so as to effect depreciationof such flimsy securing means.

Another object of my invention is to pro- I vide a paradox for a bowhaving at least one of its metallic limbs adapted to be removablysecured thereto merely by projecting the handle end of the limb into anend socket of the paradox with applied pressure and which willeffectually hold such limb in place without the possibility ofdisplacement during use.

Another object of myinvention is to provide a bow limb rece1v1ng paradoxfor an archers bow adapted to removably hold the 4 use without anyrelative rotation of the limb dox.

Another object of my invention is to provide an improved handle orparadox for an archers bow which will be most eflicient in use, whichwill stiffen the mid part of'the bow during use and securely hold thelimbs of the bow in place and which may be produced in quantities in arelatively inexpensive manner.

Referring now to the drawings: Fig. 1 shows in elevation a bow embodyingthe principles of my invention.

F1g. 2 is a longitudinal medial section through the paradox thereofshown en- Fig. 6 is a perspective view of a resilient liner extendinwithin the paradox throughout its lengt and defining the resilientsockets for the shank ends of the bow-limbs. Fig. 7 is a perspectiveview of the paradox supporting tube.

Fig. 8 is a rear elevational view of end fragments of one of the likebow-limbs, and

ignated by like reference characters, at 1 no aradox section 3 whichjoins the halvestogether.

The paradox 3 comprises a supporting tube 4, hand grip 5, preferabl ofcork or like material with 6 and 7 soldered or ot erwise secured to thetube securing the cork hand grip in place, like end caps 8 telescopedover the two ends of the tube 4, the end caps being apertured as shownat 9, Figs. 4 and 10, for the reception of the shank portions such as 1of the bow halves or l1mbs,.1 and 2. the paradox, I provide a sockettube 11 of approximately T-shaped cross-sectional form made preferablyof steel with resilient walls, which extends from end to end within thetube 4 and is tightly wedged into position therein with itslongitudinally extending curved wall 12 held tightly .in engagement withan inner wall of the tube by virtue-of the pressure inserted by a pair 0wood strips 13 and 14 serving as fillers fitting in' the tube 4 betweenthe medial rib 15 of the socket tube 11 and the opposing inside walls ofthe tube 4 and at the same time making compressive engagement with theinturned wall portions 16 of the socket tube so as to force the curvedwall 12 thereof in 1 force than would benormally applied in the ti htfitting engagement with the inner wal o the paradox tube.

The cross-sectional form of the sockets provided by the tube 11 such asthat shown at 17 Fig. 6, conforms sufliciently closely to thecross-sectional form of the shanks 10 of the bow-halves so that asnug-fitting engagement may be had within the socket tube between itsinner walls and the outer walls of the bow limb shanks.

As will be seen by reference to Figs. 8 and 9, although the bow limbstaper generally, as shown by Fig. 1, from the paradox en s of the limbstoward their tips 18 each supporting the cord 19, the shanks 10 of thebow limbs taper slightly toward their ends 20, which are chamfered asshown at 21, to facilitate easy introduction of the shanks into theirsockets by the perforated openings 9 of the paradox caps.

It will be understood, of course, that these openings 9 will be inlongitudinal allgmnent with the socket tube 11 so that a bow limb shankprojected through one of the apertures 9 will be invariably directedthereby into one of the open ends 17 of the socket tube 11.

The edges 22 of the openings 9 are also chamfered toward their outermostportions as indicated best at 23, Fig.2, to facilitate introduction ofthe shanks 10 of the bow limbs.

The socket tube 11 may be made of a seamless tube of cylindrical form orit may be made with a seam which preferably, however, will be brazedeither before or after the formation of the tube into the form of aflanged co ars .ally overcoming socket as illustrated in Fig. 6..v Theseamed construction permits the tube 11 to be made from a strip of metalrather than from a tube, thus cutting down the cost of production. y I

It will be understood that when thetapered shanks 10 are forced intosocket passage 17, that the outward pressure exerted b the inwardtelescoping movement 0 the s anks is yieldingly resisted by theresilient walls of the tube 11 and the wood fillers 13 and 14 whichresist outward deformation of said walls and by tllf resiliency of thewood material, restore the walls to non-expanded form immediately whenthe bow limb is removed.

Although the bow limbs may be separately removable, I prefer to secureone of the bow limbs such as the bow limb 2 in place as illustrated inFig. 2, so tightly that it will-re sist removal by pull much more thanthe f other bow limb. I may secure this result bow limb 2 with thesocket or as by placby coating the shank of the adhesive beforeinserting it in in any other suitable way'such ing a wire in the socketso as eiiectve cross-sectional area prior to insertion of the shankwhich then must be pressed on by the application of considerably greaterinsertion of or removal of the other bow limb in its socket.

It will be understood that although I have illustrated and describedboth bow limbs as being removable from the paradox by manuthe effects ofthe frictional contact had between ner walls of their sockets receivingthem, that I contemplate also the above described construction whereinone of the bow limbs is always retained-in its socket preferably by theuse of an adhesive.

By referring also to Fig. 9, it will be seen that the shanks of the bowlimbs are not quite straight but partake somewhat of the naturalcurvature of the bow limbs and effects a tighter wedging of the limbs inthe metallic tubular socket 12 than would otherwise be the case sincethe socket passage does not normally partake of this curvature anresiliently resists being deformed, slightly, responsive to therojection of the slightly curved shanks 10 into the sockets.

It will be seen that the lateral ribs 24 and the medial rib 25 of thebow-limbs project into corresponding sockets of the recess and thatrelative rotation of. the socket and bow limbs is thereby effectuallyprevented. The caps 8 soldered or otherwise rigidly secured to the endsof the paradox tube 4 when the bow limbs are in place projecting throughthe perforations 9 of the caps, effectually prevent any relatitverotation of the bow limbs and socket tube 11 relative to the paradoxtube 4.

the shanks and the into decrease its By reference particularly to Figs.2 and 3, it will be seen that the ends of the bow limbs approach butpreferably do not contact with each other, a space 26 being preferablyleft between the ends of the bow limb shanks when these have been forcedinwardly as far as is possible. The curvature of the bow limbs and thedegree of taper given them in their shank portions, operate topractically prevent further projection of the shanks into the sockets.

Having thus described my invention in a specific embodiment, I am awarethat numerous and extensive departures may be made from the embodimentherein illustrated and described but without departing from the spiritof my invention.
